Odin-OSIRIS detection of the Chelyabinsk meteor

On February 15th, 2013 the Chelyabinsk meteor exploded at 23 km altitude, scattering approximately 11,000 tons of material and causing the most energetic impact event since the 1908 Tunguska blast. Some of this material was ejected into the stratosphere in a large mushroom cloud and was subsequently detected by the Ozone Mapping and Profiler Suite (OMPS). This work confirms the presence and lifetime of the stratospheric debris using the Optical Spectrograph and InfraRed Imaging System (OSIRIS) onboard the Odin satellite. Although OSIRIS coverage begins in mid-March, the measurements show a high-altitude polar belt of enhanced scattering present until May of 2013.
